its pretty much a intake noise muffler...and yes you can rremove it...i dont have one on my 4.7. but I have a different intake than you.Cool, I think i will do that. My friend works at the dealership so he can get me mopar plugs.
What is the purpose of that air intake box thingy? is it removable if i extend the air intake tube? Will it make a difference?
